E. C. SCOTT CARTON CONSTRUCTION Filed July 28, 1941 2 Sheets-Sheet 2Patented Aug. 17, 1943 CARTON ooNs'rnuorion Edward C. Scott, Chicago,IiL, assignor to Ace Carton Corporation, Cicero, 111., a corporation ofIllinois Application July 25,1941, Serial No. 404,280 Claims. (01.corpse) This invention relates to containers, and more particularly tolight and economical containers for the shipping, storing, anddispensing of rolls of tape.

In the handlingshippingand storing of rolls of tape, and particularlytape such as masking tape, decorative tinsel, and the like, which may ormay not be provided with an adhesive backing, it is desirableto providea light and simple container which permits ready access to the con-,

tents and yet provides a maximum amount of protection against injury tothe outerv layers of tape in case the container should be dropped orstruck.

To this end, it has heretofore been proposed to provide a containerhaving a roll-centering device adapted to be inserted in the usual largecentral opening in a roll of tape and retain said roll in spacedrelationship with respect to the peripheral confines of the container.This manner of supporting rolls of tape prevents pressure upon orcontact with the periphery of the rolLand prevents distortion ormutilation of the tape.

However, roll-centering cartons'of the character above described areexpensive'and difiicult to manufactur and ordinarily require a largenumber of complicated gluing and assembling operations which increasetheir cost in time and labor, and materially reduce thefeasibility of.

the use of such cartons. Furthermore, the constructions heretoforeproposed frequently require thesecuring together of several separateparts into a single unit with the manifold gluing and sealing operationsthus entailed.

It is therefore an object of the present invention to provide a simple,economical, and efiicient roll-centering carton of the character setforth, wherein the necessary folding, securing, and sealing operationsare reduced to a minimum and a satisfactory roll-centering enclosure isprovided. H

Another object of the present invention is to provide a simple, compact,roll-centering carton formed from a single blank requiringa singlegluing operation for its assembly and including a simple andv improvedmeans for centering the roll oftape with respect to. the, side ,walls ofthe carton.

. It is also an object of this invention to provide a carton which maybe stored or'shipped fiat in. order to save space but which, whenrequired for use, may readily be manipulated into roll-loading position.

- Still another object oft-he present invention is to provide acontainer construction which aifords a maximum amount of protection toits contents both from physical blows and damage, and from dust andair-borne germs. I

An additional objector the invention is to provide a single piececontainer blank whereby, with a single gluing operation, there isprovided a roll-centering carton which may readily be folded andassembled in roll-carrying position.

Another feature of the present device is its utility as a combinationshipping, storing and tape dispensing device, and it will be noted thatthe roll may be left in place on the central hub and portions removedfrom time to time as required for use. Access to the roll for dispensingpurposes may be effected at either end of the carton merely by unfoldingthe desired end flap. It is therefore an object of the present inventionto provide a convenientsingle piece tape dispensing carton of thecharacter described.

Other objects and advantages will appear from a consideration of thefollowing detailed speci- .fication. For a more complete understandingof this invention reference may now be had to the drawings, in which: 7

and end walls 2, 3, 4 and 5 Which may be folded along the score lines 6,1, 8 and 9, respectively,

to provide opposite side and end walls for the carton.

The side Walls 3 and 5 maybe provided withtabs H) which are to be tuckedin before the end walls are folded into place. The end walls 2 and 4have extensions H and i2, respectively; forming end flaps each of whichis integral with the? adjacent end wall and provided with transversescore lines FE and I4 to facilitate foldingthe end flap into' placeduring the cartonclosing operatiOI-I'.

The side walls 3 and 5- am provided-with oxtensio-n's- [5 and PS-respectively, each ofwhich is creased along a transverse score .line H.The extension FG- is pr'oi' i d'ed with a shortstub 3 creased on scoreline' f9. The extension E 5 may be provided with a forming tongue 20*,having score lines 2 5, E2 and 23, defining portions 25, 25 and 2ii. 7

In assembling the carton front the above d'escribed time. thesideextension :8 together the ortion [3 is first folded inwardlyalong'tfie associated score line ii to the dotted line posio tio'n shownin Fig. The op osite extension- I 5 togetiier with the tongue 25 isthen' folded in wardiy along" the similar score FF. When theseextensionsare so folded, the securing ertions H 8 and Z6 overlap and maybe seeure'd together' gluing; stapling, or other suitable means. y I

After ti ie sid'e extensions have been ecured te gather as aforesaid,the carton, altho'u 1' 1 stantially flat and therefore in condi t forstorageor shipping,- is" ready for immediateuse. The single gluingoperation above recited is the only step necessary to provide a cartonassembly reaay'te be loaded and closed.

The cartons may be opened; loadedtvith rolls of tape; and" closed;ei'ther by'hand orby suitable automatic machinery. The 7 openingoperation the side walls a and 5 up into the position indicated bydotted lines Fig. With the tongue 29 S'ucliraised position, the rolr 21may then he slipped into place from oneend of thecarton and the tongueportion 29 pressed down-- wardly so as to contact the inner rif-i-g '28of the roll 2-1 and the portion 26 is thus folded along score lines i9,2|, 22 and 23 to make the central hub or s indle u on which the roll issu ported whileit is inthe box and atom: which it may rotate as ta e iswithdrawn from the roll and dispensed from the carton.

Itwill be noted that with this construction the simple act of inwardly(repress-- g tlle ioiig i 2'8 forms the central hub for the roll withoutany additionalgluing or securing step.

In Figs. 1 and 2' one oit-h'e end naps s shown closed while-the other isShown open. The end flaps l l and i are ex hsions upon the endwalls 2and respectively, and,-

of the transverse score line M on or the end flaps, they may readily befolded and tuel-ied into place as illustrated. Each of the end flaps ispreferably provided with suitable notches 29 or other hub portionengaging means whereby, as the end flap is tucked into place, the hubwalls is and 24 enter the notches 29 and are rigidly retained inposition thereby, as illustrated in detail in Fig. 5.

Thus: it will be seerrwith the above embodiment that merely inserting.the end flap into position causes the slots automatically to engage andsecure the hub in position and lock all of the parts in a manner bestadapted to resist the strains which may be imposed upon the carton.

Furthermore, one end flap is always in hub supporting position duringthe entire tape dispensing operation;

The tongue26, as shown best in Fig. 8, is provided with laterany prtijectingportions 36 and 3-4 which are creased along" score" lines 32' and whenfolded outwardly,- provide additional wallsfor the hub of the carton asindicated in Fig. 7. With this construction the inner portion of thecari is: completely enc1osed ,-aii"ording maximum protection to'th-e'iaside of the roll, aridthe' opening-loadingand closing operations arethe same as. in the embodiment heretoforedescribed. In

this embodiment the inwardly projecting hub is likewise securelyretained in place by the notches 29 crime erm ne In the embo imerit'disclosed in Figs. 9, l0 and 11, wherein similar parts are againidentified by the same reference numerals,- the eentralor base portion tis shownformed with a central open-- ing 34 provided with inwardldirectediiaps 35 and 36.- With this arrangement the intermediate portionE5 0 1* the hub tongue is secured in its foldedposition by means of theflaps 35 and 36 un'der wnicn it is slipped as indicated in Fig. 1e andby" which it securely retained place. Withthis arrangement the roll hubis secured at both its inner portion 25 and its outer portion to thetopand bottom oi the container, insuring a maximumrigidity within thelimits of the characteristics of the material of w-hi'chthecartonisfo'rm'edi 1 While particular embodiments of the invention have'beei'ishown, it 'will be understood, of course, that it is not desired thatthe invention be limited thereto since many modifications may be made,and it is; therefore; contemplated by the appended claims to cover suchmodincations as fall within the true spirit and scope of the invention.7
